SERIES E-7000
Digital Power Supply / Readout Systems
> Digital Single Channel Module
Bronkhorst High-Tech B.V., manufacturers of advanced mass flow
metering and control systems, offer the Digital Single Channel
Control Module for use with Thermal Mass Flow Controllers, Pressure
Controllers and other transmitters and transducers or, as in master/
slave control systems, in combination with these.
The Bronkhorst High-Tech E-7000 Series is designed to easily enable
the user through a menu format to program and power one Mass
Flow Meter/Controller, Pressure Transducer/Controller or other device.
The micro-processor based unit offers great flexibility in indication of
tags, fluid names and counter units in combination with measuring
and setpoint values, both in percentages or actual units. Furthermore
p
olynomial functions of max. 8 calibration curves, offering an accuracy
of t ± 0,5% off reading plus ± 0,1% off full scale, can be stored.
